Quantum-Classical Coexistence Network Tomography
Xuchuang Wang, Joseph C. Chapman, Aneesh Ramaswamy +5
Quantum-classical coexistence networks (QCNs) share optical fiber between quantum and classical signals via wavelength-division multiplexing, offering a practical path to quantum c…
Analysis of polarization drift of optical signals over deployed aerial-inground fiber connections
Aneesh Ramaswamy, Nageswara S. V. Rao, Joseph C. Chapman +1
Polarization measurements of a classical 1550-nm signal are collected and analyzed on 15-km hybrid aerial-inground fiber connections over 11 months. The spectral area and spectral…
Degenerate mirrorless lasing in thermal vapors
Aneesh Ramaswamy, Dmitry Budker, Simon Rochester +5
Theoretical predictions were made for the steady-state gain of an orthogonally polarized probe field in a degenerate two-level alkali atom system driven by a linearly polarized con…
Electron Beam Characterization via Quantum Coherent Optical Magnetometry
Nicolas DeStefano, Saeed Pegahan, Aneesh Ramaswamy +8
We present a quantum optics-based detection method for determining the position and current of an electron beam. As electrons pass through a dilute vapor of rubidium atoms, their m…
